NUR 426 Exam 2: Community Health Nursing Theory &
Application V3 - Arizona College Updated and Latest
Questions and Correct Answers with Rationale
1. A community health nurse is conducting a windshield survey of a low-income neighborhood. Which
observation most accurately indicates a potential environmental health hazard?
A. Absence of public transportation stops
B. Presence of overgrown vacant lots
C. High density of fast-food restaurants
D. Heavy traffic congestion near a residential playground
Ans: D
Explanation: The correct answer is B because heavy traffic near a playground poses direct risks from air
pollution and physical safety hazards. Windshield surveys are essential tools for identifying immediate
environmental threats in a specific geographic area. While fast food and lack of transport are social
determinants, they represent secondary health influences rather than immediate physical hazards.
Overgrown lots may harbor pests, but active traffic emissions are a more acute respiratory threat to
children. Identifying these hazards allows the nurse to prioritize interventions that protect the most
vulnerable community members.
2. Which action by the occupational health nurse demonstrates the use of the epidemiological triad in
workplace safety?
A. Providing seasonal flu vaccinations to all employees
B. Analyzing the relationship between repetitive motion, workstation height, and employee wrist pain
C. Ensuring the company is compliant with federal OSHA regulations
,D. Conducting a seminar on stress management for management staff
Ans: B
Explanation: The correct answer is B as it addresses the interaction between the host, agent, and
environment. The host is the employee, the agent is the repetitive motion, and the environment is the
workstation setup. By analyzing these three factors, the nurse can identify specific causes of injury and
implement targeted solutions. OSHA compliance is a legal requirement but does not strictly utilize the
triad for individual case analysis. This systemic approach helps in developing comprehensive ergonomic
programs to prevent chronic musculoskeletal disorders.
3. A nurse is planning a primary prevention program for a community with high rates of Type 2 Diabetes.
Which intervention should the nurse include?
A. Monitoring blood glucose levels of at-risk individuals
B. Teaching a low-glycemic cooking class to healthy teenagers
C. Providing foot care clinics for patients with neuropathy
D. Referring patients with pre-diabetes to a weight loss clinic
Ans: B
Explanation: The correct answer is B because primary prevention focuses on preventing the disease
before it occurs in a population. Educating healthy teenagers about nutrition prevents the physiological
changes that lead to insulin resistance. Monitoring blood glucose is a secondary prevention measure
aimed at early detection. Foot care clinics represent tertiary prevention, as they focus on managing
complications of an existing disease. By targeting younger populations, the nurse aims to shift long-term
community health outcomes through behavioral change.
, 4. During a disaster response, a triage nurse uses the START system. A victim is breathing at 24 breaths/min,
has a capillary refill of 1.5 seconds, and can follow simple commands but has a compound fracture. Which
tag is appropriate?
A. Red (Immediate)
B. Yellow (Delayed)
C. Green (Minor)
D. Black (Deceased)
Ans: B
Explanation: The correct answer is B because the victim meets all physiological stability criteria but has
a significant injury requiring care. Under the START system, if respirations are under 30, perfusion is
adequate, and mental status is intact, the patient is not ‘Immediate.’ However, a compound fracture
prevents the patient from being classified as ‘Minor’ or ‘Green’ because they likely cannot walk. Yellow
tags are reserved for those who are stable but require systemic medical attention within a few hours.
This ensures that the most life-threatening cases are prioritized while still accounting for serious injuries.
5. In the context of community health, which statement best defines the concept of ‘Aggregate’?
A. A group of people living in the same geographic zip code
B. The total population of a city regardless of health status
C. A family unit receiving home health services
D. A collection of individuals who share one or more personal or environmental characteristics
Ans: D
Explanation: The correct answer is B because an aggregate is defined by shared characteristics rather
than just geography. This could include groups like pregnant teenagers, elderly veterans, or workers in a
